According to the Organization for Economic Cooperation and Development (OECD), the rate of high speed wireless Internet access versus population in Korea reached 100.6 percent in 2011.
Wait, does that mean there are more Internet users in Korea than there are people? No, not really. OECD measures the number of high speed internet services and technologies to generate the score. Included in OECD's definition of high speed wireless internet services are 3G and 4G mobile networks, broadband, and WiFi.
Compared to the OECD average of 54.3 percent, South Korea is leading the herd by a mile. Sweden scored second at 98 percent, followed by Finland at 87.8 percent, and Japan at 82.4 percent.
Experts say Korea's rapid adoption of smartphones and 4G services is the key to their high penetration rate.
